Compress the contents of a directory while copying data into it
Hi guys

I have a need to compress the contents of a directory while I am copying data into it. I was able to do this when it was only one file by doing as below:

STEP1: mknod myfile p

STEP2: chmod 777 myfile

STEP3: compress -v < myfile > myfile.Z &

STEP4: cp -p xyz_file myfile

STEP5: rm myfile

But now my requirement is to have multiple files copied into a directory and compress while the copying is happening so that I dont use a lot of space. Can anyone of you give me some idea of how I can achieve this. For example I want to copy the contents of a directory called source (has file1, file2, file3 and file4) to backup.

Thanks in advance.

Regards

RB

MSGUNTYPOT(1p)							    Po4a Tools							    MSGUNTYPOT(1p)

NAME

       msguntypot - update PO files when a typo is fixed in POT file

SYNOPSIS

       msguntypot -o old_pot -n new_pot pofiles ...

DESCRIPTION

       When you fix a trivial error which surely doesn't affect translations (e.g.  a typo) in a POT file, you should unfuzzy the corresponding
       msgstr in the translated PO files to avoid so extra work to the translators.

       This task is difficult and error prone when done manually, and this tool is there to help doing so correctly. You just need to provide the
       two versions of the POT file: before the edition and after as marked in the above synopsis, and it all becomes automatic.

HOW TO USE IT

       In short, when you discover a typo in one of your [english] message, do the following:

       - Regenerate your POT and PO files.
	     make -C po/ update-po # for message program translations
	     debconf-updatepo	   # for debconf translations
	     po4a po4a.conf	   # for po4a based documentation translations

	   or something else, depending on your project's building settings. You know how to make sure your POT an PO files are uptodate, don't
	   you??

       - Make a copy of your POT file.
	     cp myfile.pot myfile.pot.orig

       - Make a copy of all your files.
	     mkdir po_fridge; cp *.po po_fridge

       - Fix your typo.
	   $EDITOR the_file_in_which_there_is_a_typo

       - Regenerate your POT and PO files.
	   See above.

       At this point, the typo fix fuzzied all the translations, and this unfortunate change is the only one between the PO files of your main
       directory and the one from the fridge. Here is how to solve this.

       - Discard fuzzy translation, restore the ones from the fridge.
	     cp po_fridge/*.po .

       - Manually merge the PO files with the new POT file, but taking the useless fuzzy into account.
	     msguntypot -o myfile.pot.orig -n myfile.pot *.po

       - Cleanups.
	     rm -rf myfile.pot.orig po_fridge

       You're done. The typo was eradicated from msgstr of both your POT and PO files, and the PO files were not fuzzyied in the process. Your
       translators love you already.

SEE ALSO

       Despite its name, this tool is not part of the gettext tool suite. It is instead part of po4a. More precisely, it's a random Perl script
       using the fine po4a modules. For more information about po4a, please see:
